Create and move bones using BoneList (BoneCollection) python
Ok. This was easy!
import bpy

namelist = [

(&quot;Bone&quot;),
(&quot;Bone.001&quot;),
(&quot;Bone.002&quot;),
(&quot;Bone.003&quot;)

]

for name123 in namelist:

    RIG = bpy.data.objects['Armature']

    RIG.data.edit_bones.new(('RemRoll_') + name123)
    RIG.data.edit_bones[('RemRoll_') + name123].head = RIG.data.edit_bones.get(name123).head
    RIG.data.edit_bones[('RemRoll_') + name123].tail = RIG.data.edit_bones.get(name123).tail
    RIG.data.edit_bones[('RemRoll_') + name123].roll = RIG.data.edit_bones.get(name123).roll
